PC3200 memory on 333FSB

I have seen systems advertised with a m/bd max fsb of 333MHz but the memory fitted is pc3200. I thought this memory needed a 400Mhz fsb. Obviously not if theses systems are being sold. Can anyone clarify please?? Thanks

Yes pc3200 memory ( 400Mhz ) can run on some 333Mhz cpu bus systems. The classic case is a Asus A7V8X-X motherboard. The maximum fsb of this board is 333Mhz but it will run pc3200 memory.

It is always worth reading the manual of the motherboard to determine the fastest memory you can use. Or if you know the motherboard you are interested in, put it in crucial click here to check the best memory you can put in.

just remember if you are putting memory that is not the same speed as the cpu, that you check that spd is enabled in the bios. This will run the memory at it's true speed, if it is available.
